One Line (OLine)

One Line (OLine) is a simple puzzle game. In this game, you can train your mind and imagination. The task is to connect all the points so that the individual connections do not cross or pass through other points or stones.

The game has no time limit. If you get to a point where you don't know how to proceed, you can restart the level and try to play again.
You have a limited number of undo steps to correct one of the last wrong connections.

There may be more than one correct way to connect the dots on some levels.

The game offers 3 game types:
1:
At the beginning you see one Point to start with. When you select it, you will see the other points and also one point which is the ending point (Finish Point). You have to connect all the points so that the points are connected by a single line. The last Point you have to connect is the Point that is marked as the Finish Point.
There is a second variation in this type of game. You have no defined Start Point or Finish Point on some levels. You can choose any Point as the Start Point and start connecting the other Points. In this variant, you can unselect the currently selected Point by clicking on it. You can then select a new Point and continue joining other Points.

2:
You have specified a Start Point and a Finish Point. Then there are a few more Point Alphas. When you connect a Point Alpha, a number will appear on it. This number defines the number of connections you have before you reach the next Point Alpha. If the number "1" is on the point, it means that you must already connect a Point Alpha in your next turn.

3:
You do not have defined a Start Point or Finish Point. You can start with the Point you want. However, the Point you connect will move in the direction of the connection line to the last empty cell (another Point, stone or existing connection may stop the Point's movement). You can cancel the currently selected Point by clicking on it and then continue with another Point.
